Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the engine turned off: Starting Procedure 1. With your foot off the accelerator pedal, turn the ignition to START. When the engine starts, let go of the key. The idle speed will slow down as the engine warms. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. The vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components. If the ignition key is turned to the START position, and then released when the engine begins cranking, the engine will continue cranking for a few seconds or until the vehicle starts. If the engine does not start and the key is held in START, cranking will be stopped after 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. Engine cranking can be stopped by turning the ignition switch to the ACC/ ACCESSORY or LOCK/OFF position. Notice: Cranking the engine for long periods of time, by returning the key to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down. • Audio System • Power Windows • Sunroof The radio will work when the key is in ON/RUN or ACC/ACCESSORY.

10 minutes after the engine turned off:
Audio System
Power Windows

The radio will work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from

transmission. Shift to P (Park) only when the vehicle
is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition to START. When the engine starts, let go of
the key. The idle speed will slow down as the engine
warms. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently to allow the oil to warm up and lubricate all
moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START, cranking will be stopped after 15 seconds to
prevent cranking motor damage. To prevent gear
damage, this system also prevents cranking if the
engine is already running. Engine cranking can be
stopped by turning the ignition switch to the ACC/
ACCESSORY or LOCK/OFF position.
Notice:
Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
